| 摘要 |
The invention relates to the fields of automatics, electrotechnics and can be used for multi-regime control of three-phase and four-phase step motors with permanent magnet, variable reluctance and hybrid rotors, acting in electrical drives of executive mechanisms of robots, machine tools and computer peripherals. The aim of the invention is to increase the reliability, simplicity, and to expand performance of the device. The device contains two power units with opposite polarities, logical unit power supply, two power amplifiers groups, two multiplexers groups with "1out4" structure and gating inputs, four-digit binary reversible counter, inverter, elements 2AND-NOR, 2AND, 2OR, 3AND, three non-equivalence elements, two multiplexers with "1out2" structure, two buses of setting commutation regime, gating bus of the second group of "1out4" multiplexers. The device provides 53 various commutation regimes; 24 for three-phase and 29 for four-phase step motors. |
